Empower Form

Pure arcane power surges through the target and the  target's strength is increased by your intelligence modifier and their size is increased by one on the size scale (for example: normal size creatures become large). Target can make an additional attack during their turn and they're movement is increased by the amount of your intelligence modifier times 10. Unarmed attacks deal an additional 2d4 magic damage.

Can only be used once per long rest.
